TO ALL WHOM IT -MAY CONCERN:

Be it known that I, EDWIN BIRKENSHAW, Vof Ashuelot, in the county of Cheshire, and in the State of New llampshire, have invented certain new and useful Improvements in Teasle-Maehines; and do hereby declare that thefollowing is afnll, clear, and exact description thereof, reference being had to the accompanying drawings, and the letters of reference marked thereon'.

In the annexed drawings, making a `part of this specification--l A represents a section of a teasling-gig cylinder, and

B represents the teasling-gig slats.

The cylinder A is provided with or has" a series of hooks or catches, C C, attached to it at suitable distances apart,land all standing or facing Oneway, as shown.

.The slats B are provided with projections, or have some of the cross-pieees extended out so as to slide and catch under the hooks C C. Said gig-Slat is made in the usual manner and form for holding the teasle.

D represents aspring provided n'ith a lip or catch, and is secured to thecylinder A just beneath one en'd of the slats B when adjusted, andV catches the end of said slats and holds them in place.

To detach or adjust the slats I3, I press the springD down andslide the slats out or in from orto the hooks C C, which is very quickly and readily done, as ivill be seen.

Having thus fully described my invention, what I claim as new, anddesre to secure by Letters Patent, is-

The spring D and hooks C C for holdinfr or attaehinff the o D gig-slats B, the, teasling-gig cylinder A, when constructed and arranged substantially as heroin specified.

In testimony that I claim the foregoing, I have hereunto set my hand, this 28th day of February, 1868.'
